PHG-3081 Industrial PH Meter
PHG-3081 Industrial PH Meter
PHG-3081 industrial pH meter is our latest
generation of microprocessor-based instrument, a high intelligent,
multi-function, high measurement performance, environmental adaptability and
other characteristics. It is a highly intelligent online continuous monitoring
instrument, integrate with the sensor and the second meter. Can be equipped
with three composite or two composite electrodes to meet a variety of sites.
Can be widely used for continuous monitoring of PH value for thermal power,
chemical fertilizer, metallurgy, environmental protection, pharmaceutical,
biochemical, food and water and other solution.
Features of
|
Intelligent: This industrial PH meter adopts
high-precision AD conversion and single chip microcomputer
|
|
processing technologies and can be used for the
measurement of the PH values and temperature, automatic
|
|
temperature
compensation and self-checking.
|
|
Reliability: All the components are arranged on one
circuit board. No complicated functional switch, adjusting
|
|
knob or
potentiometer arranged on this instrument.
|
|
Double high impedance input: The latest components are
adopted; The impedance of the double high impedance
|
|
input can reach as
high as l012Ω. It has strong interference immunity.
|
|
Solution grounding:
This can eliminate all the disturbance of the ground circuit.
|
|
Isolated current output: Optoelectronic isolating
technology is adopted. This meter has strong interference
|
|
immunity and the
capacity of long-distance transmission.
|
|
Communication
interface: it can be easily connected to a computer to perform monitoring and
communication.
|
|
Automatic temperature compensation: It performs automatic
temperature compensation when the temperature is
|
|
within the range of
0~99.9℃.
|
|
Water proof and
dust-proof design: Its protection grade is IP54. It is applicable for outdoor
use.
|
|
Display, menu and
notepad: It adopts menu operation, which is like that in a computer. It can
be easily
|
|
operated only
according to the prompts and without guidance of the operation manual.
|
|
Multi-parameter
display: The PH values, input mV values (or output current values),
temperature, time and status
|
|
can be displayed on
the screen at the same time.
